Answer:
Hydrostatic weighing.
Explanation:
Hydrostatic weighing may be defined as the method used to find the density or the measurement of the mass per unit volume of the living organisms. This application is based on the Archimedes principle.
The level of the body fat can also be determined by the hydrostatic weighing. The fat content of the individual body can be determined by the formula , Fat % = [4.950 /Density - 4.500]×100. The density needs to be calculated by
Density = Mass in air / Mass in air - Mass in water ÷ density of water - residual volume.
Thus, the answer is hydrostatic weighing.
Herbivores obtain energy from the plants they eat because if you are a herbivore then you only eat plants
